通过Java读取xml文件内容过程解析

package com.zyb.xml; import java.io.File;import java.util.Iterator; import org.dom4j.Attribute;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.Element;import org.dom4j.io.SAXReader; public class testXml {   public static void main(String[] args) throws Exception {    // TODO Auto-generated method stub    //1.创建SAXReader对象用于读取xml文件    SAXReader reader = new SAXReader();    //2.读取xml文件，获得Document对象    Document doc = reader.read(new File("src/book.xml"));    //3.获取根元素    Element root = doc.getRootElement();    //4.获取根元素下的所有子元素（通过迭代器）    Iterator<Element> it = root.elementIterator();    while(it.hasNext()){             Element e = it.next();      //获取id属性(attribute是属性的意思)      Attribute id = e.attribute("id");      System.out.println(id.getName()+" = "+id.getStringValue());      Element author = e.element("author");      Element money = e.element("price");      Element time = e.element("time");      System.out.println(author.getName()+" = "+author.getStringValue());      System.out.println(money.getName()+" = "+money.getData());      System.out.println(time.getName()+" = "+time.getText());      System.out.println("---------------------------------------------------------------");    }  } }
